New energy vehicles need to be charged after the electricity is used up. Due to the limitations of current battery technology and charging technology, it takes a long time to fully charge new energy vehicles, which is not as simple and fast as refueling cars directly. Therefore, in order to reduce the waiting time of users, replacing the battery when the power of new energy vehicles is almost exhausted is an effective means. In order to facilitate battery replacement and meet the battery replacement needs of more and more new energy vehicles, it is necessary to build a battery swap station. Since battery swap stations are generally built in open-air areas, they not only need to face various harsh environments, but also the charging of batteries in the battery swap station needs to be carried out at a suitable temperature. Therefore, the surrounding material on the outer frame of the battery charging area of ​​the battery swap station not only needs to have a heat preservation function, reduce the heat transfer between the inside and outside of the battery charging area, and reduce the power loss of the air conditioner, but also needs to have a high strength to avoid being damaged by bad weather.

CN211313108U discloses a mounting structure for bakelite corrugated board, including a bakelite corrugated board body, a first folding part is integrally formed on the left side of the bakelite corrugated board body, and a first mounting through hole arranged at an equal distance is opened on the top of the first folding part, and a second folding part is integrally formed on the right side of the bakelite corrugated board body, and a second mounting through hole arranged at an equal distance is opened on the top of the second folding part. When installed, the second folding part covers the first folding part. The sandwich insulation board or bakelite corrugated board structure in the above-mentioned prior art cannot meet the requirements of overall strength, thermal insulation and heat preservation of the battery swap station or energy storage station.

[0078] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0079] like Figure 6 and Figure 7 As shown, a battery swap station is illustrated according to an embodiment of the present invention.

[0080] The battery swap station includes a battery swap room 40 and at least one charging room 30 respectively arranged on one side of the battery swap room 40. The battery swap station may also include a monitoring room, a storage room, and the like.

[0081] The battery swap room 40 is used to carry vehicles whose battery packs need to be replaced. The vehicles drive into and dock at the battery swap room 40, and the battery swap cart removes the old battery packs to be charged on the vehicle and installs fully charged new battery packs. After removing the old battery packs from the vehicle, the battery swap cart transports them to the charging room 30 for charging.

[0082] The charging room 30 is equipped with a charging rack, an elevator, a main control box and other equipment. The charging rack is used to accommodate battery packs and charge old battery packs. The elevator is used to exchange battery packs with the battery swapping vehicle and to take the battery packs out of the charging rack or put them into the charging rack.

[0083] Specific as Figure 7As shown, a charging rack 31, a lift 32, a main control box 33 and other equipment are placed in the charging room 30. The charging rack 31 is used to accommodate battery packs and charge old battery packs. The lift 32 is used to exchange battery packs with the battery swapping vehicle, and to take the battery packs out of the charging rack 31 or put them into the charging rack 31. At least two rows of charging racks 31 are arranged side by side in the charging room 30 perpendicular to the driving direction of the vehicle. The lift 32 is arranged in the lifting area 34 between the two rows of charging racks 31. The main control box 33 is arranged on one side of the charging room 30 close to the battery swapping room 30. The main control box 33 is used to control the electrical equipment in the battery swapping station.

[0084] like Figure 6 As shown, the battery swap station of this embodiment forms a supporting structure through multiple frames and is divided into multiple functional rooms such as a charging room 30, a monitoring room, a storage room, etc., and the top of the frame is covered with a top plate 10, and the side of the frame is covered with a side plate 20. A door 50 for personnel and equipment to enter and exit is opened on the wall of the charging room 30 of the battery swap station.

[0085] The top plate 10 and the side plate 20 are both composed of multiple panels that can be detachably mounted on the frame, which is convenient for modular station construction, reduces costs, and is easy to disassemble and maintain. The top plate 10 and the side plate 20 are used to isolate the inside and outside of each functional room of the battery swap station, preventing external rainwater, dust and other impurities from entering the interior of the battery swap station and causing damage to electrical components in the battery swap station, such as charging racks and main control boxes. At the same time, the waterproof function of the battery swap station is improved to prevent rainwater from penetrating into the battery swap station during heavy rainfall, causing damage to the battery swap equipment and charging equipment.

[0086] The top plate 10 and the side plate 20 must have good heat preservation function to avoid the temperature in the battery swap station being too high or too low due to the external environment temperature, which will affect the battery charging and discharging performance and the service life of the equipment. Figure 1-5 The structure of a storage panel 100 used in the battery swap station of this embodiment is introduced in detail.

[0087] like Figure 1-3 As shown, in this embodiment, the storage panel 100 includes a first layer plate 101 and a second layer plate 102, a plurality of columns are arranged between the first layer plate 101 and the second layer plate 102, the first layer plate 101 and the second layer plate 102 are fixedly connected by the columns, and an insulation layer 103 is arranged between the first layer plate 101 and the second layer plate 102.

[0088] The storage panel 100 connects the first layer 101 and the second layer 102 through a column, which increases the overall strength of the storage panel 100. At the same time, an insulation layer 103 is arranged between the first layer 101 and the second layer 102, which has the function of heat insulation and reduces heat transfer, thereby ensuring the overall strength and insulation requirements of the battery swap station.

[0089] In this embodiment, the material of the thermal insulation layer 103 is one or more combinations of inorganic foaming materials, rock wool, polyurethane foam or aerogel felt.

[0090] The material of the thermal insulation layer 103 in this embodiment includes aerogel felt, which includes aerogel and glass fiber felt, and the aerogel is dispersed in the glass fiber felt. The glass fiber is used as the container of the aerogel, so that the aerogel felt has high strength, good fireproof effect, and is not easy to be damaged.

[0091] The insulation layer 103 of the storage panel 100 adopts the above-mentioned material, so that the storage panel 100 has good heat insulation and thermal insulation effects. By adding aerogel felt to the insulation layer 103, the heat insulation and fire prevention functions of the storage panel 100 can be improved, and the structural strength requirements of the battery swap station can be met while achieving lightweight storage panels.

[0092] In this embodiment, the material of the first layer 101 and the second layer 102 of the storage panel 100 is one or more combinations of SMC, carbon fiber or polymer composite materials. Preferably, SMC composite materials are used, which have excellent electrical insulation properties, mechanical properties, thermal stability, and chemical resistance. The SMC composite material is a sheet-shaped molded material formed by unsaturated polyester resin, reinforcing materials and auxiliary materials, and is formed by cutting and molding.

[0093] In other embodiments, the first layer 101, the second layer 102 and the insulation layer 103 of the storage panel 100 may also be made of other materials with excellent performance, which will not be described in detail here.

[0094] In this embodiment, the column is made of resin material. The column is made of resin material, which is convenient for processing and molding, and reduces the weight of the storage plate 100, making the storage plate 100 lightweight and convenient for transportation and installation. The resin can be unsaturated polyaldehyde resin.

[0095] Before placing the insulation layer 103 between the first plate 101 and the second plate 102, a through hole is pre-opened in the thickness direction of the insulation layer 103 to facilitate the column to pass through the through hole. By providing a through hole on the insulation layer 103, it is easy for the column to pass through, avoiding re-drilling during construction, and improving the production efficiency of the storage plate 100.

[0096] like Figure 1-3As shown, in this embodiment, the column includes a first connecting column 105 and a second connecting column 106, a plurality of first connecting columns 105 are provided on the first layer 101, and a plurality of second connecting columns 106 are provided on the second layer 102, wherein some of the second connecting columns 106 are abutted and fixed with some of the first connecting columns 105, some of the first connecting columns 105 are abutted and fixed with the second layer 102, and some of the second connecting columns 106 are abutted and fixed with the first layer 101. By arranging the columns on the first layer 101 and the second layer 102, the strength of the first layer 101 and the second layer 102 can be increased, thereby increasing the overall strength of the storage plate 100.

[0097] The first connecting column 105 and the second connecting column 106 can be connected and fixed by gluing, snapping, beads, etc. The connection method of the connecting column has a simple process, is more convenient to assemble and manufacture, and has a good fixing effect.

[0098] In this embodiment, the first connecting pillars 105 and the second connecting pillars 106 are connected and fixed to the first layer board 101, the second layer board 102, or to each other by gluing.

[0099] In other embodiments, the connection and fixation can also be carried out by snap-fitting, bead swelling or other conventional connection methods, as long as the connection strength meets the requirements.

[0100] In other embodiments, a plurality of columns may be provided only on the first layer board 101, and the columns are fixedly abutted against the second layer board 102. Alternatively, a plurality of columns may be provided only on the second layer board 102, and the columns are fixedly abutted against the first layer board 101. By providing columns on the first layer board 101 or the second layer board 102, the strength of the first layer board 101 or the second layer board 102 and the strength of the entire storage board 100 may also be increased.

[0101] In this embodiment, the first connecting column 105 is integrally formed with the first layer board 101. The second connecting column 106 is integrally formed with the second layer board 102. The above molding method is not only convenient for processing, but also can reduce the installation process, reduce the installation difficulty, and improve the connection strength of the first layer board 101 and the second layer board 102.

[0102] In this embodiment, the first layer 101 and the second layer 102 of the storage board 100 are made of SMC composite materials, and the column is made of resin, which is convenient for injection molding. When preparing the first layer 101 or the second layer 102, the mold hole of the first connecting column 105 or the second connecting column 106 is directly reserved in the mold to achieve one-time molding. This method of the storage board 100 has a simple process and higher strength.

[0103] In other embodiments, the first connecting pillar 105 and the second connecting pillar 106 may also be installed on the first layer board 101 or the second layer board 102 by welding, gluing or the like.

[0104] Of course, the column can also be made of other types of materials. For example, if the first layer 101 or the second layer 102 of the storage panel 100 is made of metal or carbon fiber material, the column can also be made of metal or carbon fiber material accordingly.

[0105] The panel 100 in this embodiment is used to be installed on the top of the battery swap station, and multiple panels 100 are assembled and spliced ​​into the top panel 10 of the battery swap station. The first layer 101 of the panel 100 serves as the upper top layer of the top panel, and the second layer 102 serves as the lower top layer of the top panel. The second layer 102 is fixed to the frame of the battery swap station.

[0106] In this embodiment, in order to facilitate drainage, the first layer 101 has a plurality of protruding units on its surface away from the second layer 102. The plurality of protruding units extend along a first direction of the first layer 101 and are arranged at intervals along a second direction of the first layer 101. The first direction is perpendicular to the second direction. By arranging the protruding units on the surface of the first layer 101 away from the second layer 102, not only the strength of the first layer 101 is increased, but also drainage is facilitated.

[0107] In this embodiment, the protruding units at both ends of the second direction of the first layer plate 101 are respectively the protruding portion 111 and the matching portion 121, the middle protruding unit is the middle protrusion 140, and the protruding portion 111 and the matching portion 121 are both higher than the middle protrusion 140. The above structure is adopted to prevent the water depth on the outer surface of the storage board 100 from overflowing the gap at the connection of the two storage boards 100 and entering between the first layer plate 101 and the second layer plate 102 when the rain is too heavy, causing water accumulation inside the storage board 100, affecting the normal use of the storage board 100.

[0108] In other embodiments, the outer surface of the first layer 101 may also be provided with protrusions at both ends, with the middle portion being a flat plate structure. Alternatively, the outer surface of the first layer 101 may also be provided with other structures that facilitate drainage or increase the strength of the storage panel 100.

[0109] In this embodiment, the protruding units formed on the outer surface of the first layer board 101 are formed by the inner surface of the first layer board 101 being recessed outward. The inner surface of the first layer board 101 is recessed outward so that a plurality of outwardly protruding cavities corresponding to the protruding units are formed on the inner surface of the first layer board 101 close to the second layer board 102.

[0110] The first layer of board 101 adopts the above-mentioned structural form to form a corrugated board structure, which can further increase the structural strength of the first layer of board 101.

[0111] Of course, in other embodiments, the middle protrusion 140 of the first layer board 101 may be a solid structure, that is, the inner surface of the first layer board 101 and the area corresponding to the middle protrusion 140 are a planar structure without a cavity.

[0112] like Figure 2 As shown, in this embodiment, a portion of the first connecting column 105 disposed on the first layer board 101 is disposed in the cavity, and a portion is disposed outside the cavity. The first connecting column 105 is disposed in the cavity of the protruding portion 111 to improve the structural strength of the protruding unit of the first layer board 101, and also to improve the connection strength at the connection of the plurality of storage boards 100.

[0113] In other embodiments, the first connecting column 105 may not be provided in the cavity, but a second connecting column 106 may be provided at a position corresponding to the cavity on the second layer board 102, and the other end of the second connecting column 106 abuts against the inner surface of the cavity.

[0114] Alternatively, in other embodiments, the first connecting pillars 105 are only arranged in the cavity on the inner surface of the first layer 101. When arranging the first connecting pillars 105, it is best to evenly distribute them on the inner surface of the first layer 101. The specific arrangement can be adjusted according to actual needs and will not be described in detail here.

[0115] In this embodiment, the column also includes an assembly column 104, which is fixed on the second layer plate 102. An assembly hole (not shown in the figure) is provided in the assembly column 104, and an assembly part 150 is installed in the assembly hole. The storage plate 100 is installed on the frame of the battery swap station, such as the supporting column of the battery swap station, through the assembly part, which facilitates the modular disassembly and assembly of the storage plate 100 and the frame, and further improves the overall strength of the battery swap station.

[0116] The second layer 102 is provided with a through hole, and the assembly hole is connected to the outside of the second layer 102 through the through hole. The frame is also provided with a mounting hole at a position corresponding to the through hole on the second layer 102. During assembly, the assembly part 150 passes through the mounting hole and the through hole on the second layer 102 and enters the assembly hole, thereby installing the storage panel 100 on the frame. The assembly part 150 may be a bolt or a buckle. By providing an assembly hole for connecting the assembly part 150 on the column of the second layer 102, the assembly of the storage panel 100 with other components can be facilitated, and the strength of the connection can be increased.

[0117] In other embodiments, the assembly hole may be replaced by other conventional connection structures, and the assembly member 150 may be replaced by other conventional connection structures.

[0118] like Figure 4-6As shown, the top plate 10 covering the top surface of the battery swap station is formed by connecting a plurality of storage panels 100. When connected, the first end of a storage panel 100 is matched and connected with the second end of the adjacent storage panel 100. In this embodiment, the first end is called the protruding end 110, and the second end is called the matching end 120. The plurality of storage panels 100 are connected and overlapped with each other through the protruding end 110 and the matching end 120. The storage panel 100 is a multi-layer composite structure, with the top and the bottom formed by the first layer 101 and the second layer 102. At the protruding end 110 and the matching end 120, the first layer 101 is bent to form a protruding portion 111 and a matching portion 121 of corresponding shapes.

[0119] At the raised end 110, the first layer 101 is raised away from the second layer 102 to form a raised portion 111. At the mating end 120, the first layer 101 is raised away from the second layer 102 to form a mating portion 121. The raised portion 111 of the first layer 101 of the raised end 110 is covered in the mating portion 121 of the first layer 101 of the mating end 120 of the adjacent connected panel 100 to form a superimposed structure, which can not only play a connecting role, connecting the adjacent panels 100 through the raised end 110 and the mating end 120 to form the top panel 10, but also play a waterproof role. The raised ends 110 and the mating ends 120 of the two adjacent panels 100 are superimposed and connected, so that water cannot directly penetrate into the joint from the outside of the panel 100, thereby improving the water tightness of the connection between the panels 100.

[0120] like Figure 5 As shown, the raised portion 111 of the first layer 101 is a trapezoidal structure, which is connected by three bends. The outer end of the first layer 101 is upwardly tilted and extended to form a first bend 112. When the first bend 112 extends to the highest point, it extends outward in the horizontal direction to form a first transition portion 114. At the farthest end of the first transition portion 114, the first layer 101 extends obliquely downward to form a second bend 113. The first bend 112 and the second bend 113 form the two oblique sides of the trapezoid, and the first transition portion 114 forms the top side of the trapezoid. The matching portion 121 of the first layer 101 is also a trapezoidal structure, and its shape matches the raised portion 111. It also has a third bend 122 and a fourth bend 123 as two oblique sides, and a second transition portion 124 as the top side.

[0121] When mating, the mating portion 121 covers and overlaps the protruding portion 111 of the adjacent storage panel 100. In this embodiment, both the protruding portion 111 and the mating portion 121 are protruding in a trapezoidal structure and overlap each other, which not only improves the structural strength of the connection of the storage panel 100, but also the protruding structure can play a role in diversion, so that rainwater at the joint can flow down along the inclined side of the trapezoid to avoid accumulation and cause rainwater to penetrate into the interior of the storage panel 100 from the joint. At the same time, the top side of the trapezoid is a plane, which can also be used to install other components.

[0122] In other embodiments, the raised portion 111 and the matching portion 121 may be set to a triangle or a semicircle according to different needs and situations, as long as they are raised in the vertical direction and adjacent storage plates 100 overlap each other.

[0123] like Figure 5 As shown, the connection between the first bending portion 112, the second bending portion 113 and the first transition portion 114 is chamfered in an arc shape, and the connection between the third bending portion 122 and the third connecting portion and the second transition portion 124 is also chamfered in an arc shape. This structure can increase the strength of the connection, facilitate rainwater to flow down from the second transition portion 124 to both sides, and at the same time make the protruding portion 111 and the matching portion 121 more closely fit in the overlapping state, further improving water tightness.

[0124] like Figure 5 As shown, the outer wall of the first bend 112 of the raised portion 111 fits the inner wall of the fourth bend 123 of the matching portion 121. This can play a waterproof role, preventing the rain level from rising when the swap station is in a rainy state and seeping into the interior of the storage panel 100 through the gap.

[0125] like Figure 5 As shown, at the overlapping structure of the protrusion 111 and the matching portion 121, there is a gap between the first layer 101 and the second layer 102. At the protruding end 110 of the storage plate 100, the edge of the second layer 102 is bent toward the first layer 101, and the edge of the first layer 101 is bent toward the second layer 102. The inner surface of the edge of the first layer 101 is attached to the outer surface of the edge of the second layer 102, forming a staggered structure to seal the inner cavity between the first layer 101 and the second layer 102.

[0126] For example Figure 5 As shown, at the mating end 120 of the storage panel 100, the edge of the second layer 102 is bent and extended toward the first layer 101, and the edge of the second layer 102 is sandwiched between the edge of the first layer 101 and the side surface of the protrusion 111 of the adjacent storage panel 100 close to the mating end 120. The outer surface of the edge of the second layer 102 is simultaneously attached to the outer surface of the edge of the first layer 101 of the protrusion end 110 of the adjacent storage panel 100. The second layer 102 is first attached to the edge of the first layer 101 of the adjacent storage panel 100, and then continues to extend upward to fill in between the first layer 101 and the first layer 101 of the adjacent storage panel 100, forming a closed structure of the storage panel 100 at the mating end 120, and also making the joint of the two storage panels 100 smaller, preventing water from seeping into the battery swap station from the joint.

[0127] like Figure 5As shown, the top of the raised portion 111 has a groove (not shown) extending along the extension direction of the storage panel 100, and a sealing strip 160 is installed in the groove. One side of the sealing strip 160 is stuck inside the groove, and the other side is against the inner side of the top of the matching portion 121. The sealing strip is arranged between the top of the raised portion 111 and the top of the matching portion 121. When rainwater accumulates on the combined unit of the storage panel 100 and causes water to rise from the gap between the raised portion 111 and the matching portion 121, it is blocked by the sealing strip 160 arranged on the top and cannot penetrate into the battery swap station, thereby improving the waterproofness of the combined unit of the storage panel 100.

[0128] In this embodiment, the sealing strip 160 is a rubber strip. In other embodiments, the sealing strip 160 can be disposed at the entrance of the fitting portion between the protruding portion 111 and the matching portion 121, or other waterproof materials can be selected.

[0129] In this embodiment, the raised end 110 and the mating end 120 of the storage plate 100 are arranged along the first direction. The two end surfaces of the storage plate 100 perpendicular to the first direction are the side parts 130, and the side parts 130 are used to close the two ends of the storage plate 100 perpendicular to the first direction, that is, the first layer 101, the second layer 102 and the side parts 130 constitute a closed cavity. The part of the side part 130 located at the raised end 110 is the first side panel, and the part of the side part 130 located at the mating end 120 is the second side panel. The second side panel covers part of the outer side of the first side panel of the adjacent storage plate 100, splices and wraps the first side panel, so that the joints of the two are staggered, preventing liquid from penetrating into the storage plate 100 from the joints on the sides of the two storage plates 100.

[0130] The battery swap station of the present invention is not limited to Figure 6 The structure of the storage panel 100 provided by the present invention is also applicable to battery swap stations with other structures or layouts.

[0131] Likewise, the structure of the storage panel 100 provided by the present invention is also applicable to energy storage stations with storage and charging functions.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
